ID Parameter CL Setting range
[Default]
Description
5607 Voltage control 2 Off Voltage control is not carried out.
[PID analog] The voltage is controlled using an
analog PID controller.
3pos controller The voltage is controlled using a
three-step controller.
AVR
Note: (Accessible only in easYgen
3400XT/3500XT)
The voltage is controlled by using
an internal AVR algorithm acting
on the “easYgen | exciter-10”
(EX-10) or AVRbridge-10-P1
module.
Note: With enabling the AVR
function the power factor control
(kvar control) is provided as well
over this algorithm. The setting
5625 Power factor control is faded
out.
5608 Voltage control initial
state 2 0.0 to 100.0%
[50.0%]
The value entered for this
parameter is the start reference
point for the analog output to the
voltage controller.
If the output to the voltage control
has been disabled, the output will
act as a control position reference
point.
5610 Proportional gain 2 0.01 to 100.00
[1.00]
The proportional coefficient
specifies the gain. By increasing
the gain, the response is
increased to permit larger
corrections to the variable to be
controlled. The farther out of
tolerance the process is the larger
the response action is to return
the process to the tolerance band.
If the gain is configured too high,
the result is excessive overshoot/
undershoot of the desired value.
Notes
This parameter is only visible if
voltage control (parameter
╚═▷
5607 ) is configured to "PID
analog".
5611 Integral gain 2 0.01 to 100.00
[1.00]
The integral gain identifies the I
part of the PID controller. The
integral gain corrects for any
offset (between setpoint and
process variable) automatically
over time by shifting the
proportioning band. Reset
automatically changes the output
requirements until the process
variable and the setpoint are the
same. This parameter permits the
user to adjust how quickly the
reset attempts to correct for any
offset. The integral gain constant
must be greater than the
derivative time constant. If the
integral gain constant is too large,
the engine will continually
oscillate. If the integral gain
